Jurassic. Morrison Formation. Morrison Formation is a series of sedimentary rocks deposited during the Jurassic Period in western North America, from Montana to New Mexico. The Morrison Formation is famous for its dinosaur fossils, which have been collected for more than a century, beginning with a find near the town of Morrison, Colorado, in 1877. Radiometric dating indicates that the Morrison Formation is between 148 million and 155 million years old.
